Question about Akai LCT2715 27 in. LCD Television
Do you a schematic diagram on this Power Supply? I have bulged (bad) EC9, EC10, EC18, EC19, and EC20 Caps. I also have shorted Zener Diodes Z3, Z4 and Z5. I believe Z3 in a 27v zener, but do not know the values of Z4 or Z5. There also may be another shorted diode below HS1. Any component values or help will be appreciated.
Here are the values for the parts:
R104 and R105 are 100 ohms 5% 1 watt but you can use 2 watts.
R107 is 200 ohms 5% 1 or 2 watts.
C17 is 2200pF 10% 1Kv.

If I give you the values of Z3, Z4 and Z5, would you return the favor by telling me what are the values for R104, R106, R107 and C17?
I have posted this request 5 times for 2 months and no body gave me an answer. Would you be willing to work with me? E-mail me email@example.com and use MLT168A-fixya as subject

You can find the service manuals at:

I have an LCT2701TD which I've been trying to get to work with no success (yet). It has a MLT166A power supply, but I bet it's pretty similar to the MLT168A. So my question to you guys is: how do you know what to replace (other than obviously bulging capacitors)? I replaced the bulging capacitors (EC18, EC19, and EC20) and the Z3 zener diode and still no success. I have a multimeter, so should I just start removing capacitors and diodes and testing them one by one?!?! Please give me some pointers if you can.
